Feb. 17, 1948. H. CAPRA ELECTRICALLY HEATED CONVECTION RADIATOR FiledApril 27, 1946 Patented Feb. 17, 1948 UNITED STATES PATENT ELECTRICALLYHEATED CONVECTION RADIATOR Horace Capra, Montreal, Quebec, CanadaApplication April 27. 1946, Serial No. 665,427 In Canada November 29,1945 4 Claims. (Cl. 219-38) The present invention pertains to a novelelectric radiator designed particularly for local and supplementalheating, although the entire heating system of a buildin may consist ofa number of such radiators. V I

The principal object of the invention is to provide an inexpensive andefficient device of this character made of a relatively small number ofsim le and inexpensive parts. The device comprises a housing having apair of spaced insulating disks between which are arranged a number ofbrackets carrying an appropriate number of insulating bushings. One ofthe disks carries a pair of binding posts. Two resistance elementsextend from one of the posts through some of the bushings and theopposite disk and back throug other bushings to the remaining bindingpost. A screen is mounted in front of the resistance elements to absorband radiate the heat.

Another feature of the invention consists in the provision of anapertured bafile adjacent to the forward wall of the housing forretarding the flow of the heated air. The forward wall is also aperturedopposite the bafiie to permit escape of the heated air into the room.The bafile is so positioned with respect to the apertures in the forwardwall as to retard the heated air and maintain it for a longer period oftime at the lower levels where it is more useful.

The invention is fully disclosed by way of ex ample in the followingdescription and in the accompanying drawings in which:

Figure l is a transverse vertical section of the device;

Figure 2 is a front elevation of the device, broken away in parts toshow several vertical planes;

Figure 3 is a detail vertical section; and

Figure 4 is a detail plan section of the invention.

Reference to these'views will now be made by use of like characterswhich are employed to designate corresponding parts throughout.

In Figures 1 and 2 is shown an inverted U- shaped base I having verticalfront and rear walls 2 and 3 respectively. The upper edge of the wallsare flanged inward at 4 and have a top plate or cover 5 fitted thereon.End walls 6 join the walls 2 and 3 and are fastened thereto in anysuitable manner. It will be understood, however, that the housing asdescribed is completed only after the internal parts have beenassembled, as will now be set forth.

Upon the base I is mounted a longitudinally extending U-shaped member Ihaving one of its sides 8 shorter than the other, for a purpose thatwill presently be described. The ends 9 of this member are also turnedup. as shown in Figure 1. and support insulating disks I0. Between thedisks a series of vertical brackets l l is suitably fastened to thebottom ofthe member I. These brackets may. for example, havehorizontalbases l2 welded or otherwise secured to the member 1. Eachbracket mounts four insulating bush- 4 ings l3 ali ned horizontally andvertically, as

shown in Figure 2, for a purpose that will presently appear.

One of the disks l8 carries a pair of binding posts M as shown inFigures 1 and 4. A pair of resistance wires l5 and I 6 have one endconnected to one of the posts, are threaded through some of the bushingsl3 and the opposite disk H]. are returned through other bushings I 3 andfinally have their remaining ends connected to the remaining ost 14.Each wire consists of two horizontal strands disposed in a given horizotal plane as shown in Figure 4. Thus. the upper wire [5 passes throughthe upper bushing [13. and the remaining wire I6 passes through thelower bushings [3. The left-hand disk ID in Figure 1 also has fourapertures to permit threading both wires back and forth therethrough.The wires may consist of any suitable resistant metal and are preferablyturned in a fine coil as shown.

To the shorter leg 8 of the member I is fastened a vertical screen I!extending upwardly somewhat beyond the upper wire l5, as shown inFigure 1. The screen absorbs heat from the wires and radiates it moreuniformly. An inclined baflle I8 has its lower end welded at l9 to theforward wall 2 and its upper end flanged horizontally at 20 along thecover 5, although it need not be directly attached thereto. The baffleI8 has two horizontal series of apertures 2| which permit the heated airto pass but at a retarded rate. The forward wall 2 also has twohorizontal series of similar apertures 22 elevated somewhat from theapertures 2|. The heated air, in following the irregular path thusprovided, is retarded and thereby maintained at the comparatively lowerlevels where it is most useful.

Although a specific embodiment of the invention has been illustrated anddescribed, it will be understood that various alterations in the detailsof construction may be made without departing from the scope of theinvention as indicated by the appended claims.

What I claim as my invention is:

1. An electric radiator comprising a housing, a pair of spacedinsulating members therein, brackets mounted between said members,insulating bushings mounted in said brackets, binding posts on one ofsaid members, resistance elements fastened to one of said posts,threaded through said bushings and the other disk and finally attachedto the remaining post, and an angular bafiie extending from the forwardwall to the top of said housing, said baflie and forward Wall beingapertured,

2. An electric radiator comprising a housing, a pair of spacedinsulating members therein, brackets mounted between said membersinsulating bushings mounted in said brackets, binding posts a. pair ofspaced insulating members therein, brackets mounted between saidmembers, insulating bushings mounted in said brackets binding' posts onone of said members, resistance ele- 1 merits fastened to one of saidposts, threaded through said bushing and the other disk and finallyattached to the remaining post, and an 25 Number angular baffieextending from the forward wall to the top of said housing, said baflieand forward wall being apertured, the apertures in said baflie being ata lower level than those in said wall.

4. An electric radiator comprising a housing, a pair of spacedinsulating members therein, brackets mounted between said members,insulating bushings mounted in said brackets binding posts on one ofsaid members, resistance elements fastened to one of said posts,threaded through said bushing and the other disk and finally attached tothe remaining post, and an angular baflie extending from the forwardwall to the top of said housing, said bafiie and forward wall beingapertured, the apertures in said baffle and wall being at differentlevels, and a screen in said housing forward of said elements.

HORACE CAPRA.
